(2) Breeding methods. With seed propagation, Chuxiong Prefecture is suitable for winter sowing. It can be planted in the middle or late October of each year with a spacing of 33 cm, a plant spacing of 16-26 cm, a sowing depth of 3-7 cm, compaction after sowing, and seeding per acre. 1.5-3 kg.
(3) Field management.
Inter-miao: According to the spacing of 16-26 cm around the seedlings.
Irrigation and drainage: During the flowering period, the soil should be kept moist, and the drought should be filled with water. When the rainfall increases, the temperature is high, and the drainage should be digged in time to reduce the occurrence of pests and diseases.
Dressing: the first time before and after the seedlings, topdressing, lightly lifting the seedlings, the second time during the bud, the application rate is 5 kg of ammonium sulfate per mu.
Soil: After the stem has been safflowered, the upper part of the safflower has many branches and is easy to fall down. Therefore, the soil is cultivated in early March.
Topping: After the safflowers pumped the stems, they removed the top buds, which promoted the increase of branches, increased the number of buds, and increased the yield of safflower.
